Method for manufacturing an aluminum alloy rod head

ABSTRACT

A method for manufacturing an aluminum alloy rod head, wherein an aluminum alloy material is placed in molds of a panel, an upper cover, and a bottom plate; and then the molds are mold-cast to be formed as casings. The inner surfaces of the casings are installed with transversal enhancing bodies and longitudinal enhancing bodies. Therefore, the weight can be controlled easily and the ratio of the thickness thereof is also controlled easily. Moreover, the mold can be removed conveniently. Then, the connections of the casings are welded to be formed as a super large (above 330CC) rod head.

BACKGROUND OF THE INVENTION

[0001] The present invention relates to a method for manufacturing an aluminum alloy rod head, wherein an aluminum alloy material is place in molds of a panel, an upper cover, and a bottom plate; and then the molds are mold-cast to be formed an the casings. The inner surfaces of the casting are installed with transversal enhancing bodies and longitudinal enhancing bodies. Therefore, the weight can be controlled easily and the ratio of the thickness thereof is also controlled easily. Moreover, the mold can be removed conveniently. Then, the connections of the casings are welded to be formed as a super large (above 330 CC) rod head.

[0002] Currently, the golf club is made by mold-casting an upper cover, a panel and a bottom plate. The rod head of the golf club made of mold-casting still has the following disadvantages:

[0003] 1. Since the conventional rod head of the gold club is formed with an upper cover, a panel, and a bottom plate which only enhances by longitudinal enhancing ribs. If a lager rod head is desired to be manufactured, then the panel must be thinner and the thicknesses of the bottom plate and the upper cover are reduced. As a result, the strength of the rod head is not enough.

[0004] 2. The mold casting of the upper casing, panel and bottom plate can not used to enlarge the volume of the rod head so as to be confined in a rod head with a small volume. Consequently, the demand is reduced.

[0005] The aforesaid defects effect the strength of the golf rod head. Therefore, the manufacturers make all their efforts to enlarge the volume of a rod head and thus to increase the strength of the panel. Furthermore, since the weight of the rod head is confined, it is only to enlarge the volume of the rod head so as to improve the strength of the panel. As a result, a super large (above 330 CC) rod head with a standard weight, a large strength and a hardness is provided.

SUMMARY OF THE INVENTION

[0006] Accordingly, the primary object of the present invention is to provide a method for manufacturing an aluminum alloy rod head which may improve the defects in the prior art. The feature of the present invention is:

[0007] 1. In the present invention, the panel, upper cover, and bottom plate of the rod head are formed individually so that the inner surfaces of the casting are installed with transversal enhancing bodies and longitudinal enhancing bodies. Therefore, the mold can be removed conveniently.

[0008] 2. In the present invention, the panel, upper cover, and bottom plate of the rod head are formed individually so that the inner surfaces of the casting are installed with transversal enhancing bodies and longitudinal enhancing bodies. Therefore, the weight can be controlled easily and the ratio of the thickness thereof is also controlled easily. Furthermore, a super large rod head is formed, and the volume of the rod head can be enlarged with the beating efficiency.

[0009] 3. The present invention provides a super large (above 330 CC) rod head with a panel of a great strength.

[0010] The various objects and advantages of the present invention will be more readily understood from the following detailed description when read in conjunction with the appended drawing.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0015] In order that those skilled in the art can further understand the present invention, a description will be described in the following in details. However, these descriptions and the appended drawings are only used to cause those skilled in the art to understand the objects, features, and characteristics of the present invention, but not to used to confine the scope and spirit of the present invention defined in the appended claims.

[0016] Referring to FIGS. 2 and 3, the method for manufacturing an aluminum alloy rod head according to the present invention is illustrated. In the present invention, an aluminum alloy material capable of controlling weight and ratio of the thickness is preprocessed so as to become a material of plasticity. The aluminum alloy material is placed in molds (not show) of the panel, upper cover, and bottom plate. The upper and lower molds are mold-cast to be formed as the casings of an panel 1, an upper cover 2, and a bottom plate 3, which are then welded to become a super large rod head. The structures of the panel 1, upper cover 2 and the bottom plate 3 will be further described in the following. The upper and lower sides of the back side of the panel 1 are protruded with transversal enhancing bodies 10 and 11. The upper and lower transversal enhancing bodies 10 and 11 are combined to be formed with a central recess 12 two sides of which are installed with longitudinal enhancing bodies 13 for enhancing the strength of the panel 1. The inner surface of the upper cover 2 near the two sides is downwards protruded with transversal enhancing bodies 20. The inner surface of the bottom plate 3 near the two sides are protruded upwards with transversal enhancing bodies 30. Then, the connections of the casings are welded to be formed as a super large (above 330 CC) rod head.

[0017] Moreover, FIG. 4 shows another embodiment of the present invention, in that, the longitudinal and transversal enhancing bodies 40 and 41 on the back sides of the panel 4 are crossed across one another so as to increase the strength of the panel 4.

[0018] The present invention is thus described, it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the spirit and scope of the present invention, and all such modifications as would be obvious to one skilled in the art are intended to be included within the scope of the following claims.
